Air conditioning does not blow cold air all the time

I have a 1997 Nissan Altima. I live in Phoenix and as you can guess it is hot. The air conditioning comes and goes. It will blow cold and then 10-15 minutes it will stop blowing cold air. I had freon put in but that did not help. Let me know what you think.

Look at the front of you A/C compressor with your A/C sent to max. the front of it should be moving with the rest of the pulley, if not you most likely have a leak and it's out of freon. If it's moving and still no cool are careful touch the pipes coming from the compressor, one is you hi side and the other low side. The smaller one (hi) should be warm or hot... the other (low) should be cold and sweating. If the clutch on the compressor is moving and those lines aren't hot and cold then your low on freon.

Hi!
It
appears we have an Air lock scenario and you will need to perform a
system Bleed.
Park
the vehicle on level ground, when cold remove coolant filler cap,
start engine and leave to idle, turn heater on full and blower to
max. When engine reaches operating temperature watch and listen near
coolant filler, keep clear as gurgling and hopefully a boil over
should occur. Top up with very warm coolant and wait as it may do it
again.
Check
for heat inside vehicle if warm replace coolant cap but keep an eye
on temperature gauge as the ~Air lock may have moved on from heater
matrix/core so proceedure needs to be carried out again from COLD.

air will always come out of vents but unless u have your a/c button pressed in and light on your a/c pump will remain disengaged and not use any more gas try tuneup and check tire press. to regain fuel economy
